Check if there are any leaks after denter's silicon application. If it's good then best is to leave it as it is. Who knows, when you get it pulled for fresh silicon application, new leaks maybe introduced if the applicator does a sloppy job.
However, if there are leaks and water is coming in the cabin, then don't delay it and get it fixed properly. Otherwise, your roof liner will be badly stained and the leaking area will slowly become rusty and get wider as it is collecting moisture now.
